Title: Element for active matrix
Inventor: SATO TAKUO
IPC: G02F1/1365
Filed: 1989-02-23
Abstract: PURPOSE:To stabilize current voltage characteristics for switching driving and to display bidirectional characteristics which have superior symmetry by providing a light shielding metal layer which prevent the photoconductivity of a semiconductor layer from varying between two 1st electrode layers and a transparent substrate across a transparent insulating layer. CONSTITUTION:On the transparent substrate 10, the light shielding metal layer 50 and transparent insulating layer 60 are laminated, and the two 1st electrode layers 21 and 22 are provided thereupon at an interval; and the semiconductor layer 30 is further laminated and a 2nd electrode 40 is laminated thereupon to constitute the active matrix element. Consequently, light from the side of the substrate 10 never enters the semiconductor layer 30 to prevent its photoconductivity from varying. Further, when the overlap areas between the electrode layers 21 and 22 and metal layer 50 are denoted as A and B, the symmetry at the time of switching driving by an AC voltage is lost because of a difference in capacity when a range of 1/3B<=A<=3B is exceeded, so the bidirectional characteristics are not obtained and a flicker is generated.
